The Andaman Islands sit in the Bay of Bengal about 1,400 km from mainland India — and they reward visitors with turquoise lagoons, untouched coral reefs, and beaches that rival anything in Southeast Asia. But the experience changes dramatically depending on when you visit.
This guide breaks down the Andaman weather month by month so you can pick the window that fits your budget, your interests, and your tolerance for rain.
Quick Answer
October to May is the best window. Within that, November to February is peak season — calm seas, clear skies, perfect for snorkelling and scuba diving. March to May is hotter but still dry, with thinner crowds and lower hotel rates.
Month-by-Month Breakdown
October — The Season Opens
The southwest monsoon retreats by mid-October. Seas begin to calm, ferries resume regular schedules to Havelock and Neil Island, and dive shops reopen. Expect occasional showers but mostly clear afternoons. Hotel rates are still off-season low — a smart time to visit if you don't mind brief rain.
Temperature: 25–30°C Rainfall: Moderate Crowd level: Low
November — Perfect Balance
Rain drops to a minimum, humidity eases, and the water visibility improves to 15–25 metres. Coral reefs around Havelock's Elephant Beach and Neil Island's Sitapur come alive. This is arguably the single best month — good weather without peak-season pricing.
Temperature: 24–30°C Rainfall: Low Crowd level: Medium
December to February — Peak Season
This is when Andaman is at its absolute best. Flat seas, 25+ metre visibility for diving, and pleasant evenings around 23°C. The trade-off: hotels book out weeks in advance, ferry tickets need early reservation, and prices peak around Christmas and New Year.
If you're planning a honeymoon or a family holiday during school break, book at least 6–8 weeks ahead.
Temperature: 23–29°C Rainfall: Minimal Crowd level: High
March to May — Hot but Uncrowded
Temperatures climb to 32–34°C and humidity rises, but the sea remains calm and swimmable. This is the sweet spot for budget travellers — hotel rates drop 20–30% from peak, and popular spots like Radhanagar Beach are far less packed. Carry sunscreen and hydrate often.
Temperature: 27–34°C Rainfall: Very low Crowd level: Low–Medium
June to September — Monsoon (Avoid)
The southwest monsoon hits hard. Expect heavy rainfall, rough seas, cancelled ferries, and many resorts and water-sports operators shut down. Unless you specifically want a rainforest experience with zero tourists, skip this window entirely.
Temperature: 24–30°C Rainfall: Very heavy Crowd level: Minimal
Best Time by Activity
- Scuba diving & snorkeling: November to February (best visibility)
- Honeymoon: November or February (romantic weather, manageable crowds)
- Budget travel: March to May or October (off-peak rates)
- Photography: November (golden light, green landscapes after monsoon)
- Family holidays: December to January (school break, calm seas)
How to Get There
